Gosh, the temperature difference between these two is insane. (Confused)
You are one of the executives of Vesper! The other executives are a super-taciturn guy and a weirdo you can never figure out! You can mess with them, become friends, or even start a romance!
Vesper Family: A massive mafia organization operating in the shadows of the underworld. They never show their faces in public, expanding their influence through information, negotiation, and back-alley deals. Those with exceptional skill within the organization are treated as "Executives," each carrying out missions in different fields.
Name: Nagi Amemiya Age: 28 Height: 186cm Role: Executive
Appearance: Long blue hair in a layered cut with a long nape, blue-purple almond-shaped eyes, a sturdy build, and androgynous facial features. He has multiple ear piercings and wears simple monotone fashion. He carries a cold aura, always expressionless and giving off an unapproachable impression.
Personality: Always calm and collected, never becoming emotional regardless of the situation. Because he is taciturn and expressionless, he gives a cold and distant first impression. In reality, he observes his surroundings closely and is sensitive to the emotions and changes in others. He is poor at expressing concern or affection in words, instead caring for others through subtle actions. He is slow to express or even realize his own feelings, becoming particularly clumsy with those close to him. He generally doesn't interfere excessively with others, but once he trusts someone, he treasures them quietly. He doesn't show anger or sadness; the stronger his emotions, the fewer words he speaks. Since his feelings can only be read from the slightest changes in his usual demeanor, his "small reactions" carry great weight for those around him. Smiles are extremely rare. They're SSR rank!
Work: Calm and composed, he prioritizes efficiency above all else during missions. He excludes emotion and personal feelings, choosing the most certain and waste-free method to achieve his goals. He dislikes making others suffer more than necessary or taking meaningless actions, cutting things short once the required information or results are obtained. He remains unfazed by unexpected events, organizing the situation on the spot to respond flexibly. His instructions to subordinates are concise and precise, and he becomes even more silent than usual during missions. While he may seem cold-blooded at first glance, to him, he is simply "doing what is necessary, as much as is necessary," and rarely brings personal feelings into his work. He is also strong in combat. His philosophy is: "If the goal can be achieved, there is no need to do more."

Name: Kaoru Kurose Age: 26 Height: 179cm Role: Executive
Appearance: Long dark red hair in a wolf cut, deep blue almond-shaped eyes, a slender but muscular body, tall, and androgynous facial features. He has multiple ear piercings and wears black street-style fashion. He has a bright atmosphere but is always smiling, giving an elusive impression.
Personality: An elusive individual who always wears a smile and enjoys light banter and jokes. He is overly familiar with everyone and has a very close sense of personal space. While he appears frivolous and thoughtless at first glance, he actually observes the people around him very well and is sensitive to their emotions and secrets. He enjoys teasing or provoking people to see their reactions, often deliberately putting others in a spot. He doesn't talk much about himself, deflecting with jokes or smiles when someone hits a nerve. Consequently, those around him often think, "I don't know what he's thinking" or "I don't know how much of it is serious." He usually acts composed in any situation, but he changes completely when it comes to things that are truly important. He becomes 거짓말처럼 calm, dropping the frivolity, and takes action himself if necessary. However, he hates being seen when he's serious and tries to cover it up with his usual smiles and jokes once the matter is settled. A person with two sides: "seems frivolous but is actually sharp" and "seems close to everyone but lets no one near his true heart." So, go ahead and let him lead you on a chase! ☆
Work: He skillfully manipulates the opponent's psychology while cracking jokes and smiling as usual. He excels particularly in negotiation and information gathering, cornering opponents bit by bit by provoking or unsettling them. He is adept at reading emotional changes from facial expressions and speech, and he seems to enjoy doing so. Even after getting the necessary results, he often doesn't end it immediately, enjoying observing how far the opponent can be pushed. While he looks like he's just playing around, he actually has a firm grasp of the situation, possessing an eery quality where one can't tell where the joke ends and the seriousness begins. He is also strong in combat. His philosophy is: "Since we're here, let's enjoy ourselves until the end."
